You are mixing non-transactional use with transactional use and this breaks things, your initial insert is in non-transactional mode but then you start a transaction so some of the changes get lost
You should always stick to one usage model, we strongly recommend transactional use Simply moving your dataset.begin(ReadWrite.WRITE); call to before you start making changes to the graph should resolve your issue Rob On 06/08/2015 14:31, "Eugene Tenkaev (Hronom)" <[email protected]> wrote: >Hello everyone! >I use Apache Jena version 2.13.0. >I try to add in existing Graph new triple by using SPARQL, and triple >didn’t added, here is the code: >public class TestTransactions { > public static void main(String[] args) { > Dataset dataset = TDBFactory.createDataset(); > DatasetGraph datasetGraph = dataset.asDatasetGraph(); > Graph graph = datasetGraph.getDefaultGraph(); > > // Fill graph. > graph.add( > new Triple( > NodeFactory.createURI("http://example/unit13";), > NodeFactory.createURI("http://example/name";), > NodeFactory.createLiteral("Unit 13", "en") > ) > ); > > graph.add( > new Triple( > NodeFactory.createURI("http://example/unit13";), > NodeFactory.createURI("http://example/type";), > NodeFactory.createURI("http://example/robot";) > ) > ); > > graph.add( > new Triple( > NodeFactory.createURI("http://example/unit13";), > NodeFactory.createURI("http://example/creationYear";), > NodeFactory.createURI("http://example/2015";) > ) > ); > > // Test. > dataset.begin(ReadWrite.WRITE); > > UpdateRequest request = > UpdateFactory.create( > "INSERT { ?s <http://example/value> '1' } WHERE { ?s ><http://example/creationYear> <http://example/2015> . }" > ); > UpdateAction.execute(request, dataset); > > dataset.commit(); > dataset.end(); > > RDFDataMgr.write(System.out, graph, RDFFormat.NTRIPLES); > } >} > >If I remove “dataset.begin(ReadWrite.WRITE);”, “dataset.commit();” and >“dataset.end();” triple will be inserted… > >Test project on GitHub https://github.com/Hronom/test-jena
